derivative of

f (x) = 7 x^{4} cot (x)

7 (4 x^{3} cot (x) - x^{4} csc^{2} (x))

Solution steps

\frac{d}{d x} (7 x^{4} cot (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 \frac{d}{d x} (x^{4} cot (x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{4}, g = cot (x)

= 7 (\frac{d}{d x} (x^{4}) cot (x) + \frac{d}{d x} (cot (x)) x^{4})

\frac{d}{d x} (x^{4}) = 4 x^{3}

\frac{d}{d x} (cot (x)) = - csc^{2} (x)

= 7 (4 x^{3} cot (x) + (- csc^{2} (x)) x^{4})

Simplify

= 7 (4 x^{3} cot (x) - x^{4} csc^{2} (x))

\frac{\partial}{\partial z} (- x z)

\int_{1}^{8} \frac{x ^{2} - 1}{x} d x

\frac{d}{d x} (y - x)

\int_{0}^{π} x \cdot sin (n x) d x

\int (3 x - 5)^{8} d x
